Basic Compressor Operation
Important Note:
This manual is provided to
allow the correct assembly and basic safe
operation of the compressor. It must be read in
conjunction with the manual that is supplied
with any other accessory intended for use with
this compressor. For more detailed information
on the use of compressors and accessories, we
strongly recommend that you purchase a good
quality publication, in order to allow you to use
this product to its full potential.
The electric motor drives an air pump which
draws in air from the atmosphere and delivers it
into the air receiver tank through the air receiver
tank supply tube. When the air pressure in the
air receiver tank reaches the operating pressure
of 8 Bar the pressure switch operates and
switches OFF the mains supply to the motor. At
the same time the air that is in the pump
cylinder, air receiver tank, supply tube and the
pressure switch is discharged. This
depressurises the pump and the pressure
regulating system allowing the pump to re-start
when the air pressure in the air receiver tank
falls below the minimum operating pressure of 6
Bar. The pressure switch is fitted with a delayed
discharge valve which will start the air pump
motor. The pressure relief safety valve is set to
operate at 8.5 Bar and is connected directly
onto the air receiver tank and will operate if the
set pressure of 8.5 Bar is exceeded should the
pressure switch fail.
Overload Protection
This compressor is fitted with an overload
protection device, In the event that the motor
becomes too hot a thermal protection device
will cut the mains supply to the motor. When the
motor temperature returns to normal, the mains
supply will be restored automatically.
Preparing For Use
Before connecting your compressor to the
mains supply, check the following:-
• The mains voltage is 230V.
• The ON/OFF switch is in the OFF (lower)
position.
• The pressure regulator should be set at its
lowest setting, i.e. turned fully anticlockwise.
• If the machine has not been used for 24
hours or so, open the drain valve to drain any
condensate which may have accumulated.
When clear, close the valve, finger tight.
Important:
If the receiver is under pressure,
keep your hands well away from the air being
expelled.... remember, compressed air is
dangerous!
Warning!
Before connecting any air tool, make
sure you have read and fully understood the
manufacturers instruction booklet for the tool
being used.
Also ensure that the tool is compatible with the
compressor and hose specifications.
If the pressure rating of the tool is less than 8
bar, the pressure regulator must be used to
adjust the output pressure.
Switching On and Off
Warning!
Switching On & Off must be done
using the On/Off switch mounted on the
compressor. Switching the compressor Off at
the mains supply can damage the motor and
will invalidate the guarantee.
Before switching on the power supply to the
compressor check that the On/Off switch is in
the Off position (pressed in) (Fig 7).
